"Don’t give up. Don’t you quit. You keep walking. You keep trying. There is help and happiness ahead. You keep your chin up. It will be all right in the end. Trust God and believe in good things to come." — Jeffrey R.
One of the keys to success is passion. If you care about something or want it naturally you won't need to force yourself to work on it. The passion will be your fuel. Only work on things you are passionate about.
